Second Order (Phi, Psi, rho, eta, theta)-Invexity Frameworks and epsilon-Efficiency Conditions for Multiobjective Fractional Programming

Abstract

A generalized framework for a class of second order (Phi, Psi, rho, eta, theta)-invexities is developed, and then some parametric
sucient eciency conditions for multiobjective fractional programming problems are established. The obtained
results generalize and unify a wider range of investigations in the literature on applications to other results on
multiobjective fractional programming.
